Working out the right position for a player

Do you spend a lot of time trying to work out the best position for a player, and who's your best player in any given position? There's already some very good advice on this forum, but when your team is in a hard-fought relegation battle (as mine is most seasons!) then you need all the help you can get.

I couldn't get the PlayerInput worksheet to work, so spent some tedious time inputting data manually on the DataOrganized worksheet. Having done that, the results have been quite useful. It helps figure out the impact of form and of energy as well as player attributes.
